Description
CROSS-REFERENCE TO RELATED APPLICATIONS

This non-provisional application claims the benefit of French Application No. 04 06296 filed on Jun. 10, 2004, and U.S. Provisional Application No. 60/579,286 filed on Jun. 15, 2004, the entire disclosures of which are incorporated herein by reference.

BACKGROUND

The present invention relates to data transfer devices, for example, suitable for use in updating the programming of a system for controlling an electric rotary machine, such as an electric motor.

Control systems typically include a memory containing values for operating parameters of a machine. These operating parameters may include parameters that govern acceleration and deceleration ranges of the machine. The parameters may include, for example, information needed to enable the machine to be controlled efficiently and may control certain characteristics of the machine, for example, its nominal voltage, power, and speed. The values may be numerous.

When these values need to be modified, a control system may be connected to a portable computer over a cable. Software running on the computer, for example, may be used to update the control system.

Alternatively, the values may be modified, for example, by using a specific console, rather than a computer. The specific console may have a liquid crystal screen or display patterns with at least seven segments. The specific console my have a keypad enabling values to be input and/or values displayed on the screen to be modified.

Proposals have also been made to modify the operational values by using a memory card containing replacement values for operating parameters. The memory card may be connected to the control system in order to transfer data. To enable a user to carry out operations needed to read the memory card, a control system must be fitted with a keypad and a screen suitable for displaying alphanumeric characters.

SUMMARY

However, there are a number of problems with these conventional methods of updating control systems. For example, modifying the values using a portable computer and software requires a specialist operator, thereby increasing the overall cost of operating the machine. Substantial cost is involved in acquiring a specific console and an operator needs to be trained in how to use the console. Thus, use of a specific console that might be cost prohibitive, for example, in respect of a one-off control system. Conventional memory cards may only be used with control systems having both a keypad and a screen. Unfortunately, such control systems are not in widespread use, in particular because they cost more and are less reliable in difficult environments.

Consequently, there exists a need to facilitate updating the programming of control systems without keypads or screens. There also exists a need to facilitate updating the programming of control systems with little risk of error, for example, accidentally loading data intended for some other control system.

Exemplary embodiments of the invention may provide a device for updating the programming of a control system of an electric rotary machine, the device having no screen. Exemplary devices may include an electrical or optical connector element for connection to the control system, enabling data to be transferred between the device and the control system and a memory for containing data to be transferred into the control system and/or for loading data from the control system. Exemplary devices may include a control member, data being exchanged between the device and the control system in response to an action exerted manually on the control member.

DETAILED DESCRIPTION OF EMBODIMENTS

FIG. 1 shows an electric rotary machine 1, such as an electric motor, for example, which may be controlled by a control system 2. For example, the control system 2 is shown as a variable speed controller enabling the speed of the motor to be varied, at least during a starting stage. However, the control system 2 may also be, for example, a starter, or any other control, protection, or monitoring member.

As shown in FIG. 2, the exemplary control system 2 may include a rotary knob 3 that is directly accessible to the user. The user may turn the knob 3, for example, to select a particular speed of rotation. The exemplary control system 2 may not have a screen. For example, the control system 2 may not have a liquid crystal display or a display with display patterns having seven or more segments. The exemplary control system 2 may not have a keypad. For example, the control system 2 may not have a keypad with at least five keys for navigating through a menu.

As shown in FIG. 2, the case 4 of the control system 2 may house a set of electronic cards including terminal strips 6 enabling the control system 2 to be connected to external components.

The control system 2 may have a connector 8, for example, a female connector having the commercial reference RJ45. The connector 8 may be suitable for connection to a data transfer device 10 (for example, shown in FIG. 3), possibly via a suitable extension lead, where necessary or desired. The connector may have five working pins, thereby leaving other pins available on the control system for connection to some other device, for example, a console having a screen, or a computer.

The data transfer device 10 may include a case 11 housing a printed circuit 12 carrying electronic components. The printed circuit 12 may be connected by a cable 13 to a connector 14, which may be, for example, a male plug having the commercial reference RJ45.

The case 11 may have an open side, as shown in FIG. 4. The case 11 may include a stud 16 on which the printed circuit 12 is engaged. A stop washer 18 may be fastened to the stud 16 so as to hold the printed circuit 12 in the case 11.

In the exemplary embodiment, the case 11 may also be covered in a flexible film 19. The printed circuit 12 may include a pushbutton 21 extending through an opening 22 of the case 11, and the pushbutton 21 may be actuated, for example, by the user actuating a control member, such as for example, pressing on a key 20 formed in the film 19.

The printed circuit 12 may carry an indicator light 22, for example, constituted by a LED. The film 19 may include a transparent region enabling light emitted thereby to be seen via an opening in the case 11.

As shown in FIG. 5, the device 10 may include a conventional integrated circuit 24, for example, of the EEPROM type (e.g., having commercial reference 24C16). The integrated circuit 24 may be fed with +5 volts from a regulator 25 and may include a memory suitable for exchanging data with the control system 2 via, for example, a line. The memory may have a capacity greater than or equal to 8 megabytes (MB), or greater than or equal to 16 MB. The line may have two wires 25 and 26, for example, connected respectively to outputs SCL and SDA of the circuit 24. The LED 22 may be powered by a transistor 28 controlled by the wire 26.

Two pins of the connector 14 may be respectively connected to the wires 25 and 26. Three other pins may be respectively connected to 0 volts, to the input of the voltage regulator 25, and to the pushbutton 21. The pushbutton 21 may be connected in series with a resistor 29 to the 0 volt connection.

Thus, in the exemplary embodiment, the control system 2 may be arranged to supply electrical power to the integrated circuit, and to the LED 22. The control system 2 may also be arranged to detect the ON or OFF state of the pushbutton 21.

The circuit 24 may store data corresponding to operating parameters for the control system 2. These operating parameters may be, for example, values for parameters serving to control an acceleration or deceleration range of the rotary machine 1 and/or values giving information about the characteristics of the machine (e.g., its nominal voltage, power, and speed).

The control system 2 may include at least one memory 60, for example, shown diagrammatically in FIG. 6. The data governing the operation of the electric rotary machine 1 may be programmed in the memory 60, the memory 60 being suitable for update by the data transfer device 10.

The control system 2 may also have at least one controller 67 such as, for example, a microcontroller or a microprocessor, and the associated peripheral components. The controller 67 may serve to control the operation of the electric rotary machine 1, and may, for example, generate signals for controlling the power electronics 62 that power the rotary machine 1. The controller 67 may serve to process information coming from sensors or other associated components.

The control system 2 may be arranged to enable the programming of its memory 60 (e.g., updated by the data transfer device 10) when a specific action is exerted on the key 20. The specific action may be, for example, two successive presses of key 20.

In the exemplary embodiment, the control system may be arranged to verify that two successive presses are performed in a predefined time interval, for example, within 0.5 seconds to 10 seconds. Thus, for example, two presses exerted in succession with a time lapse of more than 10 seconds between them will not cause data to be transferred.

Accordingly, the risk of accidentally transferring the wrong data can be kept small since merely connecting the device to the control system does not suffice to cause data to be transferred and the programming of the control system to be updated. The user must perform a voluntary action. Furthermore, the second press must be exerted quite quickly, thereby enabling an operator who has made a first press by mistake to avoid the transfer operation merely by taking care not to press a second time until said time interval has elapsed.

The data transfer device 10 may be arranged to implement a data transfer method, for example, according to the exemplary method shown in FIG. 7. As shown in FIG. 7, operation of the method begins in step 40 where a user of the electric rotary machine 1 and the associated control system 2 may define requirements in terms of, for example, operating speeds for the rotary machine 1. Then, in step 41, those requirements may be sent to, for example, the manufacturer or the distributor of the control system and the rotary machine. These requirements may be sent, for example, by e-mail.

The distributor or the manufacturer may then determine the values to be programmed in the control system 2. In step 42, the values may be stored in the integrated circuit 24. In step 43, the device 10 may be sent to the user. As a result, in step 44, the user need only connect the device 10 to the control system 2. Once connected, the user may, for example, press twice in succession on the key 20 (e.g., with a pause of about one second between the two presses) to cause the setting data contained in the memory of the device 10 to be transferred into the control system 2 and stored therein.

In the exemplary embodiment, while data is being transferred, the light 22 may flash, and once the transfer has been completed, it may remain steadily on.

Once the transfer has been performed, the user may withdraw the device 10. As a result of the exemplary method, the control system 2 may be ready to operate with the new programming corresponding to the data that has just been loaded.

Optionally, in step 45, the user may return the device 10 to the manufacturer or to the distributor.

The control system 2 may be arranged in such a manner that, once the data contained in the device 10 has been transferred, information is sent back to the device 10 and stored therein. The sent back information may include, for example, information associated with maintenance of the electric rotary machine 1 and/or of the control system 2. This information may include, for example, by a number of hours of running time. Accordingly, this information may be used to enable the manufacturer or the distributor to warn the user when maintenance needs to be carried out, so as to avoid malfunction. The information may be used to optimize operation by allowing the manufacturer or the distributor to modify certain settings again.

For a user or a distributor already possessing a data transfer device 10, the device may be programmed remotely over an interface 65, as shown in FIG. 10. The interface 65 may be connected, for example, to a computer 66 connected to the Internet.

Data needed for programming the data transfer device 10 may be sent from, for example, a server 68 of an Internet site. The Internet site, for example, may be operated by the manufacturer of the control system 2.

The interface 65 may exchange data with the computer 66 using, for example, a first protocol (e.g., RS232) and may be configured to exchange data with the data transfer device(s) 10 connected thereto using, for example, a second protocol, different from the first (e.g., I2C).

The interface 65 may also be used solely with the computer 66 with the data for programming the transfer device 10 being information keyed into, or otherwise stored in, the computer.

The software used for programming data may prompt the user for the category of the rotary machine 1 and/or the corresponding control system 2 and may automatically store in the data transfer device 10 an identity code that is specific thereto. The identity code, for example, must then be recognized by the control system 2 prior to any modification to the programming thereof.

Thus, prior to any modification of the programming, the control system 2 may check that a predefined identification code is contained in the memory of the device 10. By checking the code, the control system 2 may insure that the data to be transferred from the device 10 to the control system 2 is acceptable. This may be useful, for example, to avoid loading unsuitable data into the control system 2, for example, due to human error supposing that one device 10 has been used instead of another.

The device 10 may also be used for duplicating the values of operating parameters of the control system 2 in some other control system 2. This may be done for example, according to the exemplary method shown in FIG. 9. As shown in FIG. 9, operation of the method begins in step 50, where a user may adjust the values of certain parameters in a first control system 2. This may be done, for example, using a setting console or a computer to optimize operation of the associated electric machine 1.

Thereafter, in step 51, the user may transfer the data corresponding to the parameters into the device 10. In step 52, the user may program other control systems 2 with the same parameters, using the device 10 on each occasion.

It may thus be easy to take the programming of a control system that is judged to have been optimized, for example, a system associated with one manufacturing line, and duplicate the programming in other control systems fitted to manufacturing lines that are identical or similar, without it being necessary to perform complex manipulations and run the associated risks of error.

While various features have been described in conjunction with the exemplary embodiments outlined above, various alternatives, modifications, variations, and/or improvements of those features and/or examples may be possible. Accordingly, the examples, as set forth above, are intended to be illustrative. Various changes may be made without departing from the broad spirit and scope of the underlying principles.

For example, it is possible to make the controller 67 differently. It is possible to exchange data between the device 10 and the control system 2 other than via a wired link. For example, data may be transferred over an infrared link.

The control system 2 may be modified to present the connector 8 on a front plate, as shown in dashed lines in FIG. 1. Accordingly, a user may connect the data transfer device 10 to the control system 2 without needing to take the control system 2 apart.

The device 10 need not have its own electrical power supply, and the control system 2 may be arranged to power the device electrically. This means there is no need to provide the device 10 with an optionally rechargeable battery.

The connector may have pins for exchanging data with a computer or a console using a protocol that is different from that used for exchanging data between the device and the control system.

The action that needs to be exerted on the control member to cause data to be transferred may be other than two presses. For example, the action may be a long press of duration in excess of 1 second. The device 10 may also be made without a flexible cable between the case and the connection element of the control system. For example, the connector 14 may be carried directly by the printed circuit 12.

The above data transfer device 10 may be utilized with a range of control systems for electric rotary machines 1 having similar control systems 2. A set of data transfer devices 10, associated with the control systems may contain respectively different operating data. The data transfer devices 10 thus make it easy to program the control systems with specific data. For example, this may make it possible for the control systems to be varied to enlarge the range of systems commercially offered.

Similarly, the data transfer device 10 may be utilized within an industrial method in which electric rotary machines are controlled by respective control systems. According to the method, operating parameters may initially be determined with one of the machines and may subsequently be loaded into a device 10 prior to being transferred to at least one other control system associated with another machine.

Throughout the description the term “include” should be understood as being synonymous with “including at least one” unless specified to the contrary.

Although the present invention herein has been described with reference to particular exemplary embodiments, it is to be understood that such embodiments are merely illustrative of the broad spirit and scope of the underlying principles. It is therefore to be understood that numerous modifications may be made to the exemplary embodiments and that other arrangements may be devised without departing from the broad spirit and scope of the underlying principles.
